ZHA

Grease «ZHA» (TU 32 T 550-83) used for the laying in heated axle boxes of the cars equipped with bearings of sliding, for extra earnings of the hurt surfaces.
The basic operational characteristics:
It is antiemergency, hydrolabile. It have high break-in, lubricant and adhesive properties, good antiwear characteristics. It is efficient in the range of temperatures from-30 °С to +100 °С.

ZHRO

Grease «ZHRO» (TU 38 CT 520-83) is low-viscosity petroleum oil, solidified oil lithium soap of stearin acid, oleic acid and acids of castor oil; contains an antioxidizing additive.
Possesses high water resistance and antiscuff properties. Provides without replacement and replenishment of run of electric locomotives of 400000 km and diesel locomotives. It is efficient at temperature -40 … +120°С.
Scope: bearings of a rolling of axle boxes of railway locomotives, bearings of traction electric motors. Substitutes: LZ-TSNII, 1-13.

Data on operational temperatures represent values which are guided by a structure of lubricants, and also on a scope and technology of use. Depending on a kind of mehaniko-dynamic loading lubricants change the consistence, conditional viscosity or viscosity at various temperatures, pressure and duration of operation. These changes of indicators can affect work of components.

LZ TSNII

Grease «LZ-TSNII» (GOST 19791-74) is low-viscosity petroleum oil solidified with soda-calcium soap of acids of castor oil. «LZ-TSNII» contains antioxidizing and antiwear additives.
Possesses good antiwear and antiscuff qualities, propensity to thermohardening, the weak water resistance, insufficient conservation properties. It is efficient at temperature -40 … +100°С.
Scope:
Used in roller bearings of railway cars. Substitutes: «1-13 grease», «Litol-24@».
